Specification of Letters Patent.

Patented Nov. 28, 1916.

Application lerd February 1,8, 1916.,` lSerial No. 79,207.

To all whom t may concern.'

Be it known that I, HANS ACKERMANN, a subject of the Emperor of Germany,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented certain new and useful Improvements inLabelePasting Machines; and I` dol hereby declare the following to be afull, clear, and exact description of the invention, lsuch as willenable .others skilled inthe art to which it appertains to make and usethe same. Y

' This invention relates to machines for applying paste to labels andother paper sheets, and has for its primary object to provide a novelltype of paste applying roller in combination with meansfor guiding orlifting the labels off of theroller.y after the paste has been appliedthereto, and thus prevent the labels from adhering to the roller andbeing carried therewith into thepaste container.

Another object is the provision of means associated with the labellifting or guiding fingers fo-r removably securing the latter inoperative position with relation to the paste applying roller. Y

With these and other objects in view, the invention consists in thenovel construction combination and arrangement of parts as will behereinafter specifically described, claimed and illustrated in theaccompanying drawing, in which:

Figure 1 represents a plan view of the improved roller and guidefingers, the paste container being removed, and Fig. 2 represents atransverse sectional view through the paste container illustrating theroller and guide fingers in end elevation.Y

Referring to the drawing in detail, wherein similar reference numeralsVdesignate corresponding parts throughout the several views, the numeral5 indicates a preferred type of paste container upon which is sup*ported a shaft 6, supporting the paste-applying roller7. The roller 7 isof such diameter as to project into the container 5 and is adapted torun in the paste contained in said container.

The periphery of the roller 7 is formed with a plurality of uniformlyspaced circumferential grooves 8, receiving the curved portions 9 of aplurality of guide fingers, having straight forward ends 10 projectingforwardly of the roller 7 and over 'the front edge of the pastecontainer 5. The rear ends 11 of the fingers are directed angularly in ahorizontal plane and support a horizontally disposed bar 12. Adjacenttheir forward ends 10 the guide fingers are permanently secured to atransverse connecting rod 13. A deflector plate la, having a beveledrear edge is secured to the under portions of the straight forward ends10 of the fingers adjacent the front surface of the paste applyingroller7.

The several lingers 9 are retained in proper position with relation tothe roller 7 by a pair of, spring retaining members 15 arranged in theopposite ends of the roller 7 and having curved extremities 16 removablyengaged over the terminals ofthe rear andl front rods l2 and 13,respectively. The central portions of the retainingy members 15 extendunder and resiliently press against the lower portion of the supportingshaft 6, thereby causing the opposite curved ends 16 thereof to exertdownward pull upon the rear and front rods l2 and 13.

As clearly illustrated in Fig. 2 the outer surfaces of the curvedportions 9 of the guide fingers lie iush with the outer surface of theroller 7, and thus permit the labels or other articles to which paste isto be applied to lie fiat upon the roller and insure an evendistribution of the paste thereon. LAsthe labels are carried with theroller 7 in the directionk of rotation of the latter, as indicated byarrows in Figs. l and 2, the forward edges of the labels are engagedwith the straight forward extremities 10 of the guide fingers, 4and arethereby lifted from the roller and deposited forwardly of the latter.The guide ngers may be quickly and conveniently removed from the roller7 to permit of cleaning thereof by disengaging the ends 16 of theretaining memkbers from the rods 12 and 13, and subsequently lifting thecurved portions 9 of the guide fingers out of the grooves 8 of theroller.

What is claimed is:

1. In a pastek applying machine, a paste container, a roller supportedin said container having a plurality of uniformly spaced circumferentialgrooves, a plurality of fingers arranged in said grooves and prjectingforwardly of said roller, and a deflector plate secured to said fingershaving a beveled edge engaging said roller.

2. In a paste applying machine, a container, a roller supported in saidcontainer having a Vplurality of circumferential grooves, a plurality offingers arranged in said groo-ves and projecting forwardly of saidroller, means connecting said fingers forwardly and rearwardly of saidroller,

tainer, a shaft supported in Vsaid container,

a roller suported on said shaft having' a'plurality. of circumferentialgrooves, a plurality of guide lingers arranged in said grooves andprojecting forwardly and rearwardly of said roller, rods connected withthe opposite extremities of said ngers forwardly and rearwardly of saidroller, and spring retaining members having curved ends engaged withsaid rods and extending under Said shaft for securing said fingers inoperative position with relation to said'roller.

4. In` a paste applying machine, a container, a roller supported in saidcontainer 'S having a plurality of circumferential rooves a luralit offingers arranged in said grooves and projecting forwardly of saidroller, rodsV connected with the opposite extremities of said fingersforwardly and rearwardly of said roller, and means associated with saidrods for securing said lingers in operative position with relation tosaid roller.

5. In a paste applying machine, a container, a paste applying rollersupported in said container having a plurality of circumferentialgrooves, a plurality of fingers arranged in said grooves and projectingforwardly of said roller,.a deiector plate conynecting said fingersforwardly of said roller, rods connecting said fingers forwardly andrearwardly of said roller, and spring-re taining members, having curvedends Vengaged with said rods for securing said fingers in operativeposition with relation to said roller. v
